Electron-positron annihilation and the cosmic X-ray background

Technical Report ·
OSTI ID:5705270
;
The possibility that the processes responsible for the cosmic X-ray background (CXB) would also produce an e(-)-e(+) annihilation feature is examined. Under the assumption that these proesses are thermal, the absence of a strong e(-)-e( ) annihilation feature places constraints on the compactness (L/R ratio) of these sources. Observations favor souces of small compactness ratio.
